WS2012 Domain Controllers stop replication after Power Outage

We had some power outage and noticed newer Group Policy Objects (GPOs) weren't replicated across the AD. After running dcdiag /a diagnostic command, we noticed DRS-R event errors on some WS2012 Domain Controllers. After doing some research, we realised that WS2012 stopped auto-replication by default.

To enable it back, configure this setting on the registry and restart the affected DCs.

Set HKLM\System\CurrentControlSet\Services\DFSR\Parameters\StopReplicationOnAutoRecovery registry key to a DWORD value of 0.
